Every swimming pool owner wants to maintain their pool in the best condition with crystal-clean water. However, it is quite normal for a pool to turn green due to algae formation. So, being aware of the factors triggering algae growth in your pool will help you prevent or fix them on time, keeping your pool looking its best.
Reasons for Green Pool Problems
- Heavy Rains – Chemical imbalance occurs when rainwater mixes with pool water, making your pool vulnerable to algae formation.
- Lack of Water Circulation – Standing water encourages algae to take over your pool, turning it green.
- Hot Weather – Exposure to high heat can lead to overnight algae growth in your pool.
- Lack of Maintenance – Not maintaining your pool regularly can lead to water contamination and algae formation.
Besides algae formation, your pool could turn green due to high levels of copper.
How to Clean a Green Pool?
- Brush and Vacuum Your Pool
Brush thoroughly across your pool, including its walls, stairs, and hard-to-reach corners. This will help loosen up the accumulated algae, making it easy to clean. After – brushing your pool, vacuum it to get rid of the dust.
- Test Your Pool’s Alkalinity and pH
Alkalinity (should be 80-120 PPM) determines your pool water’s ability to withstand a change in pH levels, whereas pH levels (should be between 7.2-7.8) measure how acidic your pool water is. When these two chemicals are properly balanced, your pool water will be clean and safe.
- Shock Your Pool
Shocking involves adding chemicals to pool water to keep it balanced while increasing the free chlorine levels. A double or triple shock is necessary to get rid of algae.
- Run the Pool Filter
Turn on your pool filter post-shocking to collect and remove dead algae and other contaminants, leaving your pool with clean water.
What to Do If Algae Doesn’t Decline Even After Shocking?
If shocking does not remove greens, it may indicate that algae might not be the cause, or your cleaning process needs to be more thorough. So, ensure to:
- Test for copper and adjust its level with calcium chloride to restore its clarity
- Retest pH and alkalinity and keep them at par levels.
- Brush and vacuum again thoroughly.
- Clean, fix or replace the pool filter if it is clogged or broken.
What If My Pool Is Still Green Even with High Chlorine Levels?
In such cases, you must test your pool water’s free chlorine, which is the chlorine that must combine with the chlorinated water to sanitize the pool and kill algae. If free chlorine is low, water might turn green.

Why Is My Pool Green During Winter?
- An inadequate or dirty pool cover that allows debris and dust to accumulate.
- You are opening the pool cover too late, which increases your pool temperature, thus encouraging algae formation.
- Imbalanced pH and alkalinity levels.
